Rosetta with old 32 bit apps?

On the new M1 computers, can Rosetta run the older 32 bit apps? I read that it can operate intel apps but have not seen anything about 32 vs 64 bit.

No.


With the release of macOS 10.15 Catalina, applications will have to be 64-bit. App developers will issue updated apps if they want their apps to work on this newest macOS upgrade
